What's new
3.3.0-7.5
For The Lost Cities 7.5.1 to 7.5.6, on Minecraft 1.20.1 and Forge 47+.
Everything since 3.1.2-7.5. A building can now come in from a file, a build can be
looked at without flying round it, a touch-up comes back as the cells that changed,
a pack can be asked what it generated, and all of it runs from a server console or a
script with no game window open.
| Your game | Your Lost Cities | Download |
|---|---|---|
| 1.21.11, NeoForge | 9.4.0 to 9.5.6 | 3.2.0-9.x |
| 1.21 or 1.21.1, NeoForge | 8.0.0 to 8.4.6 | 3.2.0-8.x |
| 1.20.1, Forge | 7.5.1 to 7.5.6 | 3.3.0-7.5 |
| 1.20.1, Forge | 7.4.12 | 3.0.0 |
The commands below are in this file only. The NeoForge files are at 3.2.0 and do
not have them yet.
Bring a building in from a file
/lcdev schem place <file> puts a building on the plot you are standing on. It reads
a Sponge schematic (.schem, versions 1 to 3), a structure block's .nbt and a text
building (.json), from config/lostcitiesdevtool/schematics/. Nothing else has to
be installed.
| Question | Answer |
|---|---|
| Larger than the plot | Refused, with the row that fits it |
| Smaller than the plot | Centred. corner puts it on the plot's corner |
| What stood there | Saved as a schematic under backups/plots/, then cleared. keep pastes over it |
| A block the game does not have | Refused by name. missing places the rest |
| Stairs, panes, fences | Keep the state the file gave them |
| Chests, spawners, command blocks | Keep their data. A command block arrives unable to fire |
| The plot's settings | floors and cellars are set to the height that was placed |
schem info <file> reads a file without placing it, schem list names the files,
and schem save <name> writes the plot out as a Sponge schematic.
A height that is not a whole number of levels is one more level, part filled: a
building 21 high is four levels and generates with its roof. Measured: a tower of 123
blocks went in with its five stairs still shape=inner_left, and a townhouse of four
levels generated with every one of its 256 roof slabs.
A text building is a palette of characters and layers of rows, the same file
/lcdev look writes, so a plot can be written out, edited in a text editor and placed
again.
See a build without flying round it
/lcdev look writes a plot, or any box of the world, into
config/lostcitiesdevtool/views/:
| File | Shows |
|---|---|
sheet.png |
The four sides and the top on one image |
plans.png |
A floor plan of every level, looking down into it |
blocks.json |
Every block as text, with its state and its data |
A slab is drawn as half a square, a stair with its step, a pane edge on as a line. A line marks every chunk edge and every sixth layer, the two places Lost Cities cuts a building. A plan is taken from under a level's ceiling when it has one.
| Word | Does |
|---|---|
cut=<0 to 5> |
The layer of each level a plan looks down from |
scale=<n> |
Pixels to a block |
| A name | The folder the files go in |
A map colour is often nothing like a mod's texture. config/lostcitiesdevtool/colours.json,
a block id to "#RRGGBB", gives a block the colour you say.
See exactly what somebody changed
A touch-up is a dozen cells of a building of thousands. /lcdev diff names them.
| Command | Compares |
|---|---|
/lcdev diff |
The plot with how it stood when it was last imported or pasted |
/lcdev diff <file> |
The plot with a file |
/lcdev diff <file> <x> <y> <z> |
Any box of any dimension with a file |
Each cell says what it was, what it is, which properties differ and what happened to its data. A door left open and a chest somebody looked in are marked as use, so they can be told from a change somebody built.
/lcdev export writes the same list as changes.json beside the pack, with when and
from what each plot was filled. Measured: a pasted door, chest and command block,
untouched, differ in 0 cells; after four edits, those four.
/lcdev note <words> leaves words on the block you are looking at. look, diff and
an export hand them on with the place and the block standing there, so "a straight
stair here, not a corner" travels with the build.
A plot has to be imported or pasted with this version before diff with no file, and
changes.json, have anything to compare it with.
Ask a pack what it generated
/lcdev verify [radius], run in a dimension Lost Cities generates, reads a square of
chunks and answers with:
| It reports | So you can tell |
|---|---|
| How many chunks chose each building | Whether the weights do what was meant |
| Up to three copies of each, one of every height first | Where to go and look, with the box to look at |
| Each multibuilding placed whole | That it fits |
| The buildings no chunk chose | Which ones no city style names |
| Each chunk that failed, with the reason | What broke, without reading the log |
centre=<x>,<z> moves the square, a building's name generates that one first, and
samples=<n> gives up to eight copies. Measured on a test pack at radius 10: 408 city
chunks, 327 with a building, and for a part with an undefined character 11 failures,
each naming the character and the part. The command took 5 seconds at radius 8 and 8
at radius 32.
/lcdev findings [namespace] gives the load check's findings when asked, for one pack
or all of them. /lcdev profile set <key> <value> puts a profile key in the pack,
checked against the keys and types this Lost Cities has.
Run it from a console or a script
| Command | Does |
|---|---|
/lcdev at <plot> <command> |
Runs a command standing on a named plot, in plot coordinates. No player needed |
/lcdev json <command> |
Answers with one line of JSON: the result, the numbers, each refusal and what to change |
/lcdev script <file> |
Runs a file of commands, one a line, and stops at the first that fails |
lcdev.py, in the repository's agent folder, drives a server from a shell: start,
stop, run a command, install an exported pack, restart and report what generated. One
file, Python's standard library only. It refuses to start on a port another program
holds and names the port, takes its ports by argument, and never sends a command to a
server that is not the one it was pointed at.
So a pack can be built, exported, generated and checked by a script, on a machine with no game window.
Supported range
Unchanged: 7.5.1 through 7.5.6. The full check suite passes against 7.5.6.
Not checked

schem savehas not been opened in WorldEdit. lcdev.pyran on Windows only.
